Status for Ravens linebacker Jameel McClain remains unknown

The medical outlook for Ravens inside linebacker Jameel McClain remains a cloudy issue as coach John Harbaugh acknowledged that the team had thought previously he would have been ready for the start of training camp.

However, McClain is sidelined indefinitely on the physically unable to perform list due to the spinal cord contusion he suffered last December against the Washington Redskins. Harbaugh emphasized that the team won't take any risks with McClain and he won't be practicing until he's fully recovered.

"Jameel is a tougher one to predict because he's go the back issue, it's a spinal issue," Harbaugh said Tuesday following the first practice of training camp. "It just has to heal. Until that heals and we have proof that it's healed, he's not going to be out there.

"Doctors had anticipated he would be out there at this time. It's a little slower than we had hoped. When he's ready, he'll be out there. He's going to continue to take some more tests, and we'll have more for you on that on Thursday."

On Tuesday, Harbaugh also said cornerback Lardarius Webb won't be placed on the physically unable to perform list.

Webb is coming off a torn anterior cruciate ligament suffered last October against the Dallas Cowboys. He's ahead of schedule in his rehabilitation and practiced Tuesday on a limited basis. The Ravens will ease him into a bigger workload, but they're upbeat about his progress and he appears to be on track to play in the regular-season opener against the Denver Broncos.

"Lardarius is practicing," Harbaugh said. "We will bring him along as we see fit, but you saw him out there. He's doing well."

Pro Bowl offensive guard Marshal Yanda is on the physically unable to perform list after undergoing offseason shoulder surgery to repair a torn rotator cuff. Yanda is slated to do only walkthroughs and individual drills and no full-team work.
